  • Failure analysis showing the effect of sulphur content in stainless steel on the resistance to stress corrosion cracking in marine environments at ambient temperatures

    The risk of environmentally assisted cracking in downhole components is high due to sour conditions, i.e. the presence of hydrogen sulphide. Therefore a range of materials possessing excellent corrosion resistance are employed. However, corrosion is not only downhole related but is also a common problem on the platform deck itself due to airborne salts from ocean spray. For this reason the ...
